Hello everyone! I am evaluating web2py framework for suitability in order to accomplish one of my client's project - basically, an application reading the data from the database and displaying it on interactive charts, depending on the options chosen. Web2py seems to be a perfect choice as application is going to be used by fairly big but yet limited number of users, and the pre-configuration pre-configuration pre-configuration, DAL model and admin panel it provides perfectly suites my needs.
There is one demand I have that I cannot easily figure out from the book. I want to only allow one authenticated session at a time for an individual login in my application. When (if) I detect multiple logins using same credentials but from different machines I want to deny access to the second user and inform about the situation the first one (or other action accordingly). Regarding my studies, I fairly see it possible to fulfil this demand using web2py itself, but maybe some external libraries could help? Anyone ever faced same issue? Thank you for advice! KBS --
